mongodb 未在 ubuntu 18.04 上启动 [英] mongodb not starting on ubuntu 18.04

问题描述

我在 Windows 10 上运行 ubuntu 18.04.我在 cli 上运行 'mongod' 并且 mongodb 正常启动.然后我尝试运行mongo"并收到此错误:

I'm running ubuntu 18.04 on windows 10. I run 'mongod' on cli and mongodb starts normally. I then try to run 'mongo' and I get this error :

MongoDB shell version v4.0.2
connecting to: mongodb://127.0.0.1:27017
2018-09-01T20:30:37.462+0800 E QUERY    [js] Error: couldn't connect to server 127.0.0.1:27017, connection attempt failed: SocketException: Error connecting to 127.0.0.1:27017 :: caused by :: Connection refused :
connect@src/mongo/shell/mongo.js:257:13
@(connect):1:6
exception: connect failed.

我不明白一个是如何工作的，而另一个则不是.我确实认为这是来自文件权限或本地主机的问题.

I don't understand how one works and the other doesn't. I do think it is from either file permissions or an issue with the localhost.

推荐答案

这可能是两件事

1.) 确保您已设置/data/db 目录.

1.) Make sure you have the /data/db directory set up.

2.) 使用 sudo 启动 mongodb

2.) start mongodb with sudo

sudo start mongodb 

或

sudo service mongodb start

3.) 您可能需要删除锁定文件，请尝试以下操作:

3.) You might have to remove a lock file try the following:

sudo rm /var/lib/mongodb/mongod.lock

4.) 修复你的 mongodb 实例

4.) Repair your mongodb instance

sudo mongod --repair

5.) 尝试运行 mongo 控制台:

5.) Try running the mongo console:

mongo

6.)检查mongodb实例的状态

6.)Check the status of the mongodb instance

sudo status mongodb

如果这些不起作用，我知道 DigitalOcean 有一个很棒的教程，我已经链接了 Digital_Ocean_Tutorial

If these don't work I know DigitalOcean has a great tutorial which I have linked Digital_Ocean_Tutorial
